Polyglyceryl-4 Caprate ●
TL;DR. This ingredient is a mild nonionic surfactant, solubilizer, and emulsifier used to help disperse oils, fragrance components, and lipophilic actives in water-based formulas. It can also support gentle cleansing and improve rinse-off feel.
What does Polyglyceryl-4 Caprate do in a cosmetic formula?
This ingredient is a mild nonionic surfactant, solubilizer, and emulsifier used to help disperse oils, fragrance components, and lipophilic actives in water-based formulas. It can also support gentle cleansing and improve rinse-off feel.
Is Polyglyceryl-4 Caprate clean?
From a clean-beauty perspective, it is generally well tolerated and does not sit on major restricted lists. As with many surfactants, eye or skin sensitivity can depend on concentration and the overall formula.
Is Polyglyceryl-4 Caprate sustainable?
This material is commonly sourced from vegetable-derived glycerin and medium-chain fatty acids, often linked to coconut or palm-kernel supply chains. It is expected to be readily biodegradable, with sourcing traceability being the main sustainability question.
Is Polyglyceryl-4 Caprate COSMOS-approved?
It is permitted under COSMOS natural and organic frameworks when made from approved natural-origin feedstocks and compliant esterification chemistry. Its profile fits Green Chemistry well because it can use renewable inputs, has a favorable biodegradation profile, and does not require persistent silicone or petrochemical structures.
How does Polyglyceryl-4 Caprate work chemically?
The molecule is a nonionic amphiphile with a hydrophilic multi-glycerin head and a C10 fatty-chain ester tail, giving it oil-water bridging behavior. Typical use is often around 0.5% to 5% depending on whether the formula needs solubilizing, emulsifying, or mild cleansing, and ester stability is best in mildly acidic to neutral systems rather than strong acid or alkaline conditions.
